Description

  The present invention relates to an endoscope simple cleaning system and a simple cleaning unit for pre-cleaning a plurality of endoscopes.

  Endoscopes used in inspections, etc. are subjected to simple pre-cleaning at the bedside by the operator's hands, and then cleaned and disinfected (or sterilized) as a full-scale reprocessing process using a dedicated cleaning and disinfecting device. ) Etc. are given.

  However, even if pre-cleaning is inadequate or if pre-cleaning is performed, if there is time between pre-cleaning and reprocessing, bodily fluids and dirt are difficult to adhere to the outer surface of the endoscope. There is a possibility that it cannot be washed out even after reprocessing. Therefore, Patent Documents 1 and 2 have been proposed as solutions to this problem. Patent Literatures 1 and 2 disclose an endoscope transport case that functions as a cleaning tank. According to this transport case, a used endoscope can be pre-cleaned automatically and reliably.

On the other hand, recently, a system that can use an endoscope for rental in response to a request from a hospital or the like has been studied. In such a rental system, after inspection, used endoscopes are collected at the rental center, and the collected endoscopes are collectively reprocessed by equipment dedicated to the rental center. Considering such a rental system, the endoscope is collected from the hospital, clinic, etc. to the rental center, and therefore it takes a certain amount of time between pre-cleaning and reprocessing. Therefore, in such a rental system, it is necessary to perform pre-cleaning more reliably. In addition, when the endoscope is collected by visiting multiple hospitals, or when the rental system is applied to a traveling medical examination car equipped with equipment related to endoscopy and an environment for endoscopy It is assumed that the amount of electronic endoscopes collected at a time increases.

The connection port 7 includes a liquid supply pipe 7a connected to a liquid supply path 26, which will be described later, and a suction pipe 7b connected to a waste liquid path and a circulation path. The connection port 6 communicates with the inside of the case 3, and the connection port 6 7 includes a liquid supply pipe 6a and a suction pipe 6b. The case 3 may be sealed by attaching a sealing cover to the upper surface of the case 3.

  The configuration of the cleaning / disinfecting unit 4 will be described with reference to the block diagram of FIG. The cleaning / disinfecting unit 4 includes a cleaning liquid tank 20, a water storage tank 21, a disinfecting liquid tank 22, a waste liquid tank 23, pumps 24 a and 24 b, valves 25 a to 25 d, and a control unit 30. The control unit 30 controls the pumps 24a and 24b and the valves 25a to 25d so that the supply of the liquid stored in the tanks 20 to 22 or the discharge of the liquid from the case 3 does not overlap each other. In addition, an operation unit 31, a display unit 32, a tag reader 33, and a memory 34 are connected to the control unit 30, and each unit is operated in accordance with an operation input performed on the operation unit 31.

  The tanks 20 to 23 can be detached from the cleaning / disinfecting unit 4, and one tank is provided for each type of liquid. The pump 24a is a liquid supply pump, 24b is a waste liquid pump, the valves 25a to 25d are electromagnetic valves, the valve 25a is a four-way valve, and the valves 25b, 25c, and 25d are three-way valves. The cleaning / disinfecting unit 4 further includes a case through a valve 25a, a pump 24a, a valve 25b, and connection ports 6 and 7 from the cleaning liquid tank 20, the water storage tank 21 and the disinfecting liquid tank 22 as liquid paths through which the liquids pass. 3, a supply path 26, a connection port 6, 7, a pump 24 b, a valve 25 c, a valve 25 b, a connection port 6, 7 to the case 3, and a circulation path 27 from the circulation path 27 to the valve There is a return path 28 that branches off at 25 c and returns from the valve 25 d to the disinfecting liquid tank 22, and a waste liquid path 29 that reaches the waste liquid tank 23.

  The liquid supply path 26 branches downstream of the pump 24 a and is connected to each connection port 7. Further, a pump 24b, valves 25b and 25c, and a circulation path 27 are provided for each connection port 7. Further, the waste liquid passage 29 joins one downstream of each valve 25c and is connected to the valve 25d.

  The memory 34 stores a program for operating each unit based on the conditions of each process including cleaning, that is, the processing time, the amount of liquid to be used, and the like. This program is set as programs A, B, C... According to the unique information of the endoscope 2. As this program, for example, when the unique information of the endoscope 2 is a unique ID or model-specific information indicating an endoscope that is highly likely to be contaminated such as for large intestine, the processing time is increased or inserted. In the case of an endoscope having a long section, the output of the pumps 24a and 24b is set to be increased.

  The control unit 30 operates the RFID tag reader 38 when the power of the cleaning / disinfecting unit 4 is turned on. When the RFID tag 5 of the endoscope 2 enters a predetermined communication distance, for example, a distance of several millimeters, the RFID tag reader 38 communicates with the RFID tag 5 and reads unique information. In this embodiment, before performing the simple cleaning process, the RFID tag reader 38 reads the unique information from the RFID tag 5, and the control unit 30 reads the program from the memory 34 according to the unique information stored in the RFID tag 5. Each process is executed according to this program. If the RFID tag 5 is not read, each process is executed by a standard program in which standard processing time, liquid usage, and the like are set.

  The operation of the above configuration will be described. When the used endoscope 2 is accommodated in the case 3 and the connection ports 6 and 7 are connected to each other, the power switch is turned on to instruct the start of the simple cleaning process. In addition, the pumps 24a, 24b, valves 25a to 25d, etc. are actuated to start cleaning, rinsing (first time), disinfection, rinsing (second time), and storage steps in sequence. Table 1 shows an example of an operation pattern for the pumps 24a and 24b and the valves 25a to 25d when performing these steps. Table 1 is used for each of the cleaning, rinsing, disinfection, and storage steps. explain.

  First, when the cleaning process is started, the pump 24a is turned on and the pump 24b is turned off, and the cleaning liquid tank 20 side, the water storage tank 21 side, and the liquid supply path 26 side of the valve 25a are opened and disinfected. The liquid tank 22 side is closed. The cleaning liquid tank 20 side of the valve 25a is initially closed, and after water begins to flow from the water storage tank 21, the cleaning liquid tank 20 side is also opened for a short period of time, and the cleaning liquid is allowed to flow a little to close. Further, the liquid supply path 26 side of the valve 25b is open, the circulation path 27 side is closed, and the valves 25c and 25d are fully closed. As a result, a mixture of the cleaning liquid and water from the cleaning liquid tank 20 and the water storage tank 21 through the liquid supply path 26 is supplied to each case 3 through the liquid supply pipes 6a and 7a of the connection ports 6 and 7. Is done.

  After the cleaning liquid and water are supplied for a predetermined time until the inside of the case 3 is almost filled, the control unit 30 performs control to circulate the cleaning liquid and water. In this case, the pump 24a is turned off and the pump 24b is turned on, the valve 25a is fully closed, the valve 25b is closed on the liquid supply passage 26 side and the circulation passage 27 side is opened, and the valve 25c is opened on the circulation passage 27 side. In this state, the waste liquid passage 29 side is closed, and the valve 25d is fully closed. Accordingly, the cleaning liquid and water in the case 3 are sucked from the suction pipes 6b and 7b of the connection ports 6 and 7 by the pump 24b, and the sucked cleaning liquid and water pass through the circulation path 27 and are again connected to the connection ports 6 and 7. Therefore, the endoscope 2 is efficiently cleaned by circulating the cleaning liquid and water in each case 3. The cleaning liquid and water are mixed evenly.

  Then, when the cleaning liquid and water are circulated for a predetermined time, the control unit 30 performs control to waste the cleaning liquid and water. In this case, switching control is performed so that the valve 25b is fully closed, the valve 25c is opened on the waste liquid path 29 side and the circulation path 27 side is closed, and the valve 25d is closed on the return path 28 side and the waste liquid path 29 side is opened. Is done. As a result, the cleaning liquid and water sucked from the case 3 by the pump 24 b are discharged into the waste liquid tank 23 through the waste liquid passage 29. When this waste liquid is used, suction is performed until almost all of the cleaning liquid and water in the case 3 are exhausted.

  In Table 1, since the rinsing process is the same as the cleaning process except that the cleaning liquid tank 20 side of the valve 25a is always closed, the description of the operation pattern of the rinsing process is omitted. In the rinsing process (first time) after the cleaning process is completed, water is supplied from the water storage tank 21 to the case 3, circulated, and drained, so that the body fluid and dirt remaining in each case 3 and the cleaning liquid Is rinsed with water.

  When the rinsing process (first time) is completed, the next is the disinfection process. When the sterilization process is started, the control unit 30 starts the cleaning process except that the sterilization liquid tank 22 side and the liquid supply path 26 side of the valve 25a are open and the other tanks 21 and 22 are closed. Control is performed with the same operation pattern. As a result, the disinfecting liquid is sent from the disinfecting liquid tank 22 through the liquid supply path 26 to the liquid supplying pipes 6 a and 7 a of the connection ports 6 and 7.

  After the disinfecting liquid is supplied for a predetermined time until the inside of the case 3 is almost filled, the control unit 30 performs control for immersing the endoscope 2 in the disinfecting liquid. In this case, both the pumps 24a and 24b are turned off and the valves 25a to 25d are fully closed. Thereby, the state where the disinfecting liquid is stored in the case 3 is maintained, and the endoscope 2 immersed in the disinfecting liquid can be disinfected.

  When the endoscope 2 is immersed in the disinfecting liquid for a predetermined time, the control unit 30 performs control to return the disinfecting liquid to the disinfecting liquid tank 22. In this case, the pump 24b is ON, the waste liquid path 29 side of the valve 25c is open and the circulation path 27 side is closed, and the valve 25d is open when the return path 28 side is open and the waste liquid path 29 side is open. Switching control is performed so as to be in the closed state. As a result, the disinfecting liquid sucked from the suction pipes 6 b and 7 b of the connection ports 6 and 7 is returned to the disinfecting liquid tank 22 through the waste liquid path 29 and the return path 28. When the disinfecting liquid is returned, suction is performed until almost all the disinfecting liquid in the case 3 is exhausted.

  After the disinfection process is completed, a rinsing process (second time) is performed, which is controlled in the same manner as the operation pattern described above, and the disinfecting liquid remaining in each channel and on the outer surface of the endoscope 2 is rinsed with water.

  When the rinsing process (second time) after the disinfection process is completed, the storage process is performed in which water is stored in the case 3 and the endoscope 2 is immersed. When the storage process is started, the control unit 30 performs the cleaning / disinfecting process except that the valve 25a is in an open state with the water storage tank 21 side and the liquid supply path 26 side, and the other tanks 20 and 22 are closed. Control is performed in the same operation pattern as when starting. Thereby, water is sent from the water storage tank 21 through the liquid supply path 26 to the liquid supply pipes 6a and 7a of the connection ports 6 and 7.

  After water is supplied for a predetermined time until the inside of the case 3 is almost filled, the control unit 30 performs control to immerse the endoscope 2 in water. In this case, both the pumps 24a and 24b are turned off and the valves 25a to 25d are fully closed. Thereby, the state where water is stored in the case 3 is maintained, and the endoscope 2 is stored in a state where it is immersed in water. In this state, the endoscope 2 is transported while being accommodated in the case 3, and is subjected to a reprocessing process in a rental center or the like equipped with dedicated facilities.

  As described above, by using the simple cleaning system 1, it is possible to efficiently perform pre-cleaning including a cleaning process, a rinsing process, a disinfection process, and a storage process for a plurality of endoscopes 2. In the system 1, each of the tanks 20 to 23 and the pump 24a is provided in the cleaning / disinfecting unit 4, and these parts, the liquid supply path, and the waste liquid path are commonly used for each case 3. The number of parts can be reduced and the cost of the simple cleaning system 1 can be reduced. Furthermore, the endoscope 2 is sufficiently pre-cleaned and stored in a state in which the endoscope 2 is immersed in the case 3 in which water is stored. Therefore, after the pre-cleaning, until reprocessing is performed. During this time, even if a certain amount of time has passed, the body fluid and dirt are not fixed to the endoscope 2, and the dirt can be reliably removed by performing the reprocessing process. Further, since the unique ID of the endoscope 2 is read and the pre-cleaning conditions are changed, the pre-cleaning can always be performed under appropriate conditions.

  In the above embodiment, the box-shaped case 3 is used as the plurality of cases 3 connected to one cleaning / disinfecting unit 4. However, the present invention is not limited to this, as shown in FIG. The storage bag 50 for storing the endoscope 2 may be used as a simple cleaning tank. Further, as shown in FIG. 5, a sealing member 51 is integrated with the accommodation bag 50, and is made of, for example, a well-known fastener shape or an adhesive tape. In this case, the connection between the cleaning / disinfecting unit 4 and the storage bag 50 includes the liquid supply pipes 53a, 54a and the suction pipes 53b, 54b. The storage bag 50 is provided, and the harnesses 55 and 56 are connected to connect the cleaning / disinfecting unit 4 and the storage bag 50. By using the storage bag 50 in this way, the amount of each liquid used can be reduced and the running cost of pre-cleaning can be reduced as compared with the case where the case is used as a simple cleaning tank.

  Further, when the storage bag is used as the simple cleaning tank, the storage bag may be broken during pre-cleaning and the liquid may flow out. Therefore, as shown in FIG. However, the pre-cleaning may be performed using the storage bag 60 as a simple cleaning tank. In this case, the storage bag 60 does not have an additional function in particular, and may be any one that can withstand single use or use several times. Alternatively, as shown in FIG. 7, a plurality of storage bags 70 may be stored in one case 71, and pre-cleaning may be performed using each of the storage bags 70 as a simple cleaning tank. In this case, the pre-cleaning can be performed by storing the same number of storage bags in a smaller space than the simple cleaning system shown in FIG. In addition, when storing a plurality of storage bags in one case in this way, the storage bags 70 may be stored in a so-called flat layout, arranged at the same height, or a shelf 71a on which the storage bags 70 are placed. The accommodation bags 70 may be accommodated in a vertical arrangement.

  In the above embodiment, a case where a plurality of endoscopes are cleaned at the same time is illustrated, but the present invention is not limited to this, and a case where a plurality of endoscopes are individually cleaned with one cleaning unit. Can also respond. In this case, in the configuration of the above embodiment, parts such as the tanks 20 to 23 and the pump 24a, the liquid supply path, and the waste liquid path are commonly used. For example, as shown in FIG. When the cleaning liquid is supplied to the tank A, it is not possible to perform the control of supplying the disinfecting liquid to the tank B different from the tank A. Further, it is impossible to return the disinfectant from the tank B when the tank A is draining the cleaning liquid.

  Therefore, as a countermeasure against this, as shown in FIG. 8B, the control unit 30 performs control to delay the process of the tank B with respect to the process of the tank A so that the supply of different liquids and the waste liquid do not overlap. Do. That is, when a process other than liquid supply (circulation, waste liquid, immersion, etc.) is being performed in a case 3 and no liquid supply of other liquid is required in other cases 3, the valve 25a is fully closed. If necessary, the pump 24a is turned on and the valve 25a opens the mouth of the corresponding liquid tank. Alternatively, when a process other than waste liquid and return is being performed in a case 3 and the other liquid waste liquid and return are not required in other cases 3, the valve 25d is fully closed and required. If this happens, the pump 24b corresponding to the tank is turned ON, and the valve 25d opens the corresponding port of the waste liquid and the return. This minimizes the delay time for individual cleaning, so individual pre-cleaning can be performed efficiently when multiple endoscopes are used instead of in a medical examination car. It can be carried out.

  In the above-described embodiment, one liquid supply pipe is provided for each connection port 6 and 7, and each liquid is supplied to the simple cleaning tank. However, the present invention is not limited to this, and FIG. As shown in the storage bag 80 as a simple cleaning tank, the supply pipes 83a to 83d connected to the cleaning / disinfecting unit 4 are branched to be inserted into the insertion channel of the endoscope 2 such as air supply / water supply, suction, and forceps channels. It is good also as a structure which injects and injects a liquid. Further, in this case, the connecting means between the storage bag 80 and the cleaning / disinfecting unit 4 is the harnesses 81 and 82 in which the liquid supply pipes / suction pipes 83a to 83e are grouped. As a result, the inside of the insertion channel that is difficult to clean and cannot be cleaned can be reliably cleaned.

  The connection means between the case 3 and the cleaning / disinfecting unit 4 is preferably a group of supply and suction pipes such as a connection port and a harness from the viewpoint of preventing erroneous insertion and working efficiency, but is not limited thereto. It is only necessary to recognize which liquid supply pipe / suction pipe is connected to each case 3 side and the cleaning / disinfecting unit 4 side. For example, the liquid supply pipe / suction pipe on the case 3 side and the cleaning / disinfecting unit 4 side If the same numbers are assigned to each other and it is determined that the pipes with the same numbers are the corresponding liquid supply pipes / suction pipes, it becomes easy to recognize when connecting the liquid supply pipes / suction pipes. Or you may make it attach the same color and a mark to the liquid supply pipe | tube / suction pipe | tube of the case 3 side and the washing | cleaning disinfection unit 4 side.

  In the above embodiment, each of the cleaning liquid, water storage, disinfecting liquid, and waste liquid tanks 20 to 23 is provided in the cleaning / disinfecting unit 4 and is commonly used for each case 3, but not limited thereto. A tank for each liquid may be provided for each case 3, and a supply / waste liquid path and a circulation path may be provided for each liquid tank without using a common supply / waste liquid path and a circulation path. . Furthermore, a configuration may be adopted in which tap water is introduced by connecting to an external water supply without providing a water storage tank in the cleaning / disinfecting unit.

  In the above embodiment, the cleaning / disinfecting unit has a function of performing each process of cleaning, disinfection, rinsing, and storage, but not limited thereto, a drying process for circulating air in the simple cleaning tank, A small amount of alcohol may be injected into each channel, and a function such as a process called alcohol flush in which air is circulated and dried, and a sterilization process in which a sterilization gas is injected into a simple cleaning tank may be provided.

  In the above-described embodiment, an electronic endoscope that observes an image obtained by imaging the state of the subject using a solid-state imaging device has been described as an example, but the present invention is not limited to this, The present invention can also be applied to a simple endoscope cleaning system that employs an optical image guide to observe the state of a subject.
